<p>PROBLEM TO BE SOLVED: To provide an aerator for continuously stably conducting an aeration. SOLUTION: The aerator comprises an air supply source, a heating means for heating an air supplied from the source, a line L15 for supplying the air after heating by the heating means to a hopper 23 of a dust collector, and a constant flow valve V2 for maintaining a pressure of the air of upstream side constant to supply it to a downstream side. In this case, since a pressure of the air of upstream side from the valve V2 is maintained constant, the air of a predetermined amount is supplied to the downstream side of the valve V2 by an operation of the valve V2.</p> |
